Sending HLR-query

You can check phone numbers for availability by sending a special HLR request. As a result of the request, data will be received about the country and the subscriber's operator, about the roaming operator when the subscriber is in a foreign network, as well as about the status of the subscriber (available or not). Subscribers who are the owners of the verified numbers will not receive any notifications about the performed checks of their number.

Execution of an HLR request over the HTTP protocol is performed in the same way as sending an SMS message, and the request must pass an additional parameter hlr=1.

To send an HLR request, use the GET or POST method to call the address: https://smscentre.com/sys/send.php?login=<login>&psw=<password>&phones=<phones>&hlr=1
Other parameters that are used for sending regular SMS messages and described on this page are also available.

The result of the HLR request can be sent to the URL for receiving incoming messages and statuses specified in the settings in your personal account, or it can be read by requesting the status of the sent SMS message.

Example:
https://smscentre.com/sys/send.php?login=alex&psw=123&phones=79999999999&hlr=1
